Inside of DIALIGHT.
|
This is the inside of a dialight LED panel.
It looks like the inside has the 12 LEDs in the back, like one incandescent lamp would shine. and the sides make it aim the light to the refractor, which makes the light brighter and hides the fact that it is LED. Makes the incandescent feel.
I was VERY surprised to find out it isn't like 2 or 3 big LED's but instead it is 12 small LEDs clustered in the middle to act like a real incandescent. So maybe that theory about the 3 small LEDs aren't true.. hm.

Most of the LEDs signals have just a LEDs array that is diffuse across the lens, so the LEDs are visible across the traffic signal.
However in our german LED traffic lights this isn't the case.
When viewing with any angle, they exhibits a similar patterns of the incandescent traffic lights but with a difference lens.
Also the LEDs are HPLEDs so this signal should be very bright when looking directly
So perhaps this is the signal used in ours german LED traffic lights. They are actually very bright, even in mid day.
So that's how these non-pixelated led modules look like? BTW that thing with 12 LEDs is from Lumileds and the 12 LEDs are called Luxeon I. 1w each.
@Jace - do your red led module look like this one here?
By the way how did you open yours up?
